PROCESS OF MAKING NOZ ZLES.

Specification of Letters Patent.

Patented Apr. 16, 1912.

Application filed March 27, 1911. Serial No. 617.279.

To all whom it may concern:

Be it known that I, JAMES HALL TAYLOR, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Processes of Making Nozzles, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specifica, tion.

My invention relates to the manufacture of nozzles such as are commonly used in connection with steam boilers and it contemplates a method whereby an integral article is formed.

In present day practice, nozzles for steam boilers usually comprise two flanges connected by a tubular member, one of said flanges being riveted or bolted to the boiler and the other being similarly secured to a corresponding flange on the connecting pipe. On account of the great pressure to which these articles are subjected, it is impractical Heretofore,

to make them of cast metal. nozzles of this character have been made of at least two wrought iron parts. .Methods of connecting the two parts have been proposed and tried because of the advantages of an integral structure. I However, in these processes of making nozzles comprising two or more parts but connected so as to ,make as nearly as possible an integral structure, there are difficulties which are serious and, so far as I am aware no practical method of making integral Wrought iron nozzles has yet been found. I have proved the practicability of my invention by actual practice,

and the process which I employ results 1n a commercial nozzle of one piece of wrought metal. I

The process of my invention comprises a succession of steps which cooperate .to the end of producing a complete nozzle from a single block of wrought metal, the article of manufacture thus produced being eflicient and thoroughly safe, even considering the great strains to which it is subjected in its use as contemplated .in the art.

The process of my invention will be best understood by-illustrations showing the results of the various steps in the process.

In the accompanying drawing, Figure 1 body b so that the flange f,

is a cross-sectional view of the wrought metal ingot; Fig. 2 is a plan view of the blank after the first step in the process has been carried out; Fig. 3 is a diametrical sectional View of the member shown in Fig. 2; Fig. 4 is a view similar to Fig. 3 showing the result of the next step in the process; Fig. 5 is a view similar to Fig. 4 showing the next step in the process; Fig. 6 is a plan view of the finished nozzle; and Fig. 7 is a diametrical section of the finished nozzle.

The billet of wrought metal, from which the nozzle is to be formed, is shown at a. By the first step in the process this billet is heated and formed, by means of dies, into a circular body I) haying a flange a at the top thereof, there being, a circular depression 01 in the top of the body, concentric therewith. This is shown in Figs. 2 and 3. The blank is kept at forge heat and is then subjected to the action of dies which middle portion, as shown'in Fig. 4, so that the body I) may be brought down andthe pocket 03 enlarged to the extent of the pocket shown at d. The result is a tubular part at e. The outer part of the flange 0 remains as the flange a while the inner section, since the pocket d tapers downwardly, forms part of the tube 6, as illustrated. The next step in my process consists in flattening down the parallel to the flange c, is formed. This is illustrated in Fig. 5. It will be noted that here the part g remains to close the nozzle and the next step in my process-consists in punching out this part so that'a complete'tube may result. The finished product is illustrated in'Figs. 6 and 7 this article thus comprising the two parallel flanges 0', and f and the tapered connecting tube e.

I claim as new and desire to secure by Letters Patent: V

1. The processof forming nozzles which consists in first forming a cylindrical body with a flange, then stretching the body away from the flange and at the same time forming a concentric pocket on the top side, then smashing down the body to form a second flange, and then punching out that part of the remaining body in line with the pocket to form a complete tube.

2. The process of forming nozzles which consists in first forming a cylindrical body stretch down the I with a'fiange, then stretching the body away In witness whereof, I hereunto subscribe from the flange and at the iame'timg foi'lmmy name this 23rd day of March, A. D. 1911.

mg a concentric pocket on t e to si e, t en smashing down the body to fOII Ih a second JAMES L TAYLOR. 5 flange, and removing that part of the remaining body in line with the pocket to form a complete tube.
